FASTENER FOR WOODf-JOINTS.

SPECIFICAT forming part of Letters Patent No. 546,152, dated September10, 189 5,

Application filed Februaryl, 1395. Serial No. 533,211. (No model.)

To all wle/0m it may concern:

Be it known that I, JASPER N. HIEEONYMUS, a citizen of the UnitedStates, residing at Fairbury, in the county of Livingston and State ofIllinois, have invented certain new and useful improvements' inFasteners for food-Joints; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in wood-joints and has particularreference to a new and improved metallic fastener employed in connectionwith the same.

The objects of my invention are to produce a secure practicallyinseparable joint for two adjacent members of Wood, and to effect thesame through the medium of a cheaply constructed readily appliedmetallic fastener.

With these general objects in view the invention consists in theconstruction of joint hereinafter described and the fastener employed inconnection therewith, all as particularly pointed out in the claims.

Referring to the drawings, Figure 1 is an elevation and partialsectional view of two wood members joined inaccordance with myinvention, two of the metallic fasteners being employed. Fig. 2 is asimilar view illustrating the mode of forming a joint with a roundmember or rung and but one of the metallic fasteners. Fig. 3 is a detailin perspective of the end of the round rung or member with the fastenerapplied. Fig. 4. is a detail in perspective of the metallic fastener.Fig. 5 is an elevation of that member in which the mortise is formed butbefore the insertion of the tenon member. Fig. 6 is a similar viewillustrating the mortise as it'appears after the insertion of the tenonmember and fastener.

Like numerals of reference indicate like parts in all the figures of thedrawings.

For the purpose of convenience I will designate the two memberscomposing the joint.

as the mortise member 1 and the tenon member 2, it being understoodthatthe former is provided with the mortise 3, and in the presentinstance the latter member is provided with the tenen il. lt is to beunderstood, however, that the mortise may extend entirely through themember i, in which case the tenon on the member 2 would be omitted andthe latter member passed entirely through the member l,such arrangementbeing necessary in some structures.

The fastener is made of metal and consists of the two branches 5 and 6,the same being right-angularly disposed with relation to each other, andthe latter branch being considerably shorter than the former. The lowereX- tremity of the branch 6 is beveled at its inner side, therebyproducing a chisel-shaped driving-point 7. The upper side of theremaining branch 5 of the fastener is provided with a series ofrearwardly-inclined teeth S, the teeth extending to a point near therear extremity of the fastener. The front end of the branch 5 is beveledin conformity with the teeth, as indicated at 9. One or a plurality ofthese metallic fasteners may be employed in a joint, the formerarrangement being illustrated in Fig. 2 and the latter arrangement beingillustrated in Fig. l. These fasteners may be readily applied by forcingthe driving ends 7 into the tenons near the inner ends of the latter,the toothed portions 5 lying along the tenon and terminating near theirouter ends. Where the fasteners are employed in connection with roundrungs, and therefore round tenons, the latter are preferably flattenedon their upper sides, as indicated at 10, to form a flat surface uponwhich the fastener may rest. Having placed the fastener in position upona tenon, the latter is forced into the mortise 3, the latter being, forinstance, as shown in Fig. 5. It will be seen that as the tenon isinserted into the mortise the teeth of the fastener will form a channel,as indicated at ll, Fig. 6, the liber of the wood being forced away bythe inclined teeth, which latter, by reason of their inclination,oifering but slight obstruction to the insertion of the tenen. When,however, the tenon has become seated in the mortise, the liber of thewood that has been thus forced aside has a tendency to return, andtherefore engages with the rear edges of the teeth of the fastener andsecurely locks the tenon against withdrawal, all as clearly illustratedin Figs. l and 2. In appearance the joint is ordinary, but it will beseenA that a most effective means has been provided for preventing theWithdrawal of the tenen, and I thus obviate the use of pins or nails forsecuring the tenons in position.

It Will be understood that the fasteners may 4be formed of any suitablelength, and they may be provided with any number of teeth, which lattermay be made coarse or tine, as desired, all such changes being meremechanical skill, or as may be suggested by the character ot' work to beperformed.

Having deseribed my invention, what I claim is 1. The hereindeseribedmetallie fastener for Wood-joints, the same consisting of theright an gularly disposed branches 5 and 6, the former having the seriesof inclined transverse teeth 8, terminating short of its rear end, andits front end beveled as at 9, and the branch 6 reduced to form thechisel-edge driving-point 7, substantially as specified.

2. The combination with the member l, having the mertise 3, and themember 2, having the tenon 1, of the right angularly shaped metalfastener having the branches 5 and '7,

the former provided upon its upper side with a series of transverseteeth inclined toward the outer angle of the device, and the member 7engaging permanently with the tenen, substantially as specified.

3. The combination with the member I having the mortise 3 and the member2 having the tenen 4, of the upper and lower metallic fasteners appliedto the upper and lower sides of the tenen in a permanent manner andconsisting eaeh of the right angularly disposed branches 5 and 6, theformer having the series of inclined transverse teeth 8, and at itsfront end beveled as at 9 and the branch G reduced to form the drivingpoint 7, said teeth S engaging With the opposing Walls of the mortise 3,substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

JASPER N. I'IIERONYMUS.
